<p>Heavy metal<a> pollution</a> has become a serious global problem in soil
contamination. Cadmium (Cd) is a ubiquitous environmental toxic pollutant to
plants, which can greatly affect their growth and development, or even lead to
their death. In the present study, we performed a comparative transcriptome
analysis to identify the regulators and pathways that were involved in Cd
absorption and transportation in the roots, leaves and fruits of wild-type and
mutant pepper plants. A total of 883,591,943 million reads were mapped to the
reference genome, and 33,927 genes were identified. Sample reads and the
reference genome alignment efficiency were between 78.99% to 84.57%. Finally,
798 differentially expressed genes (DEGs) were identified in the roots, leaves
and fruits of the mutant and wild-type plants, including 80 up-regulated DEGs
and 718 down-regulated DEGs. The DGEs were mostly related to the
phenylpropanoid biosynthesis pathway and glyoxylate and dicarboxylate
metabolism. In addition, some vital DEGs were identified in
absorption/transportation-related pathways, such as ABC transporter and P-type
ATPase. The results revealed that several genes were related to the regulation
of Cd absorption and<a></a><a> transportation</a>. Collectively, our
findings provided valuable insights into the molecular mechanism of Cd
absorption and transportation in pepper.</p>
